Gud Boi 09e78ad087 Bind named `to_actor.run()` inputs with partials
PR #481 made target inputs positional and reserved keywords for
actor placement/runtime controls. PR #484 still forwarded target
kwargs, so tests and examples failed local signature binding after
the rebase.

Deats,
- bind named target inputs with `functools.partial()`
- keep placement, naming and runtime controls as direct keywords
- reject invalid target calls locally before actor startup
- require linked one-shots to raise one direct `RemoteActorError`
- doc linked context execution and per-child process reaping

Gud Boi e7f5968850 Name every `ActorNursery` binding `an` in tests/examples
Convention sweep (user req): all `tractor.open_nursery()`
bindings in test + example code use `an: ActorNursery` (`n`,
`nursery` + several tractor-nurseries confusingly named `tn`
are renamed); `trio.open_nursery()` bindings stay `tn` (incl.
`concurrent_actors_primes.py`'s inner trio nursery, renamed
`n` -> `tn` to match).

Purely mechanical, function-scoped renames — prose "nursery"/
"an" in docstrings/comments untouched; func-arg kwargs like
`portal.run(func, n=value)` untouched.

Gate: renamed test modules green on `trio`; full debugger suite
(28p/6s) + example-runner (21p) green.

Gud Boi 551090d129 Fix mutual-rendezvous premature-reap race (#477)
The `test_trynamic_trio` + `a_trynamic_first_scene.py` migration
to paired `to_actor.run()` one-shots carries a race the legacy
`run_in_actor()` shape never had: donny + gretchen each
`wait_for_actor()` (then DIAL) the *other*, but a one-shot is
reaped the instant its own hello returns — so the slower peer
can resolve the winner's registry entry and connect to an
already-dead sockaddr -> `ConnectionRefusedError` boxed as a
`RemoteActorError` (or a reg-wait `TooSlowError`), flaking
~1-in-3 standalone runs.

Mutual-rendezvous peers must OUTLIVE both dialogs, so pin the
lifetimes explicitly: `start_actor()` both as daemons, run both
hellos concurrently via bg `Portal.run()` tasks, then reap with
`an.cancel()` only after the task-nursery joins. (The legacy
teardown-reap provided this pinning implicitly — one of the
few places its semantics were ever actually relied upon.)

Gate: `-k trynamic` standalone x8 green (was flaking); full
`test_registrar` module + the example-runner green.

Gud Boi bb0a9b3c93 Remove `run_in_actor()` + the ria reap cluster
The final excision of #477: with zero in-repo callers left (all
tests/examples/docs migrated to `to_actor.run()` et al) the
entire legacy one-shot machinery drops out,

- `runtime/_supervise.py`: `ActorNursery.run_in_actor()`, the
  `._cancel_after_result_on_exit` portal-set and the
  `_reap_ria_portals()` teardown-reaper (both its happy-path
  block-exit call AND the error-path snapshot + 0.5s-bounded
  collection) are deleted — one-shot result-waiting now lives
  entirely in the caller's task via `to_actor.run()`, whose
  enclosing cancel-scope bounds the wait by construction (the
  correct-scoping fix for the unbounded-reap hang class; the
  `d1fb4a1a` guard test now passes structurally).
- `runtime/_portal.py`: `Portal._submit_for_result()`,
  `._expect_result_ctx`, `._final_result_msg/_pld`,
  `.wait_for_result()` + the deprecated `.result()` alias are
  gone — a `Portal` no longer has any "main result" notion.
  NB `Context.wait_for_result()` is a different (very alive)
  API and is untouched.
- `spawn/_spawn.py`: `exhaust_portal()` +
  `cancel_on_completion()` (the reaper tasks) deleted; backend
  comment sweeps in `_trio.py`/`_mp.py`.
- `_exceptions.py`: the `NoResult` sentinel dies with its lone
  reader.
- `tests/test_ringbuf.py`: drop a daemon-portal `.result()`
  call that was already a warn + `NoResult` no-op (the ctx-acm
  exit does the real result-wait); unshadow the 2nd `sctx` as
  `rctx`.
- comment/docstring x-ref sweeps: `msg/types.py`,
  `_context.py`, `to_actor/`, `tests/test_to_actor.py`.

Gate: `test_to_actor test_spawning test_cancellation
test_infected_asyncio test_local test_rpc` = 81 passed,
3 xfailed on `trio`; +`test_ringbuf` = 70 passed, 3 skipped,
3 xfailed on `mp_spawn`.

Gud Boi 4eca8d7a10 Port `test_dynamic_pub_sub` off `run_in_actor`
The known-flaky dynamic pubsub test's 3 fire-and-forget spawn
sites (#477 removal),

- the forever-streaming `publisher` + N `consumer` one-shots now
  bg-schedule as `to_actor.run(fn, an=n)` tasks in a local `trio`
  task-nursery (`publisher`'s rendezvous name still derives from
  `fn.__name__`).
- the simulated user-cancel raise (`KeyboardInterrupt` /
  `TooSlowError` params) cancels the task-nursery, each one-shot
  reaping its subactor via `to_actor.run()`'s shielded
  `Portal.cancel_actor()`; `_run_and_match()`'s existing
  `BaseExceptionGroup.split()` walk covers the (possibly nested)
  relay shapes unchanged.
- spawns now issue concurrently rather than sequentially —
  comment on the fork-backend budget updated to match.

Gate: both params x4 runs green on `trio` + x1 on `mp_spawn`;
full module green.

Gud Boi 3fcc4ee713 Port SIGINT + sync-sleep cancel tests off `run_in_actor`
Final `test_cancellation.py` group of the `run_in_actor` removal
(#477) — cancel-mechanics tests, so clean conversions,

- `test_cancel_via_SIGINT_other_task`: the 3 keep-alive
  `run_in_actor(sleep_forever)` one-shots become plain
  `start_actor()` daemons (an idle daemon needs no "main" task,
  and no longer shares a single dup'd `namesucka` name).
- `spawn_sub_with_sync_blocking_task`: the middle layer's spawn
  becomes a blocking `to_actor.run(spin_for, an=an)` which parks
  awaiting the sync-sleeping grandchild's result until cancelled
  from above.
- `test_cancel_while_childs_child_in_sync_sleep`: the
  fire-and-forget middle-actor spawn becomes a bg
  `to_actor.run()` task in a local task-nursery; the root's
  `assert 0` cancels it, driving the same
  graceful-cancel-then-zombie-reap cascade on the sync-blocked
  grandchild. The `man_cancel_outer` xfail param is unchanged.

Zero live `run_in_actor()` call-sites remain in this suite.

Gate: full `test_cancellation.py` module green on both `trio`
(18p/1xf) + `mp_spawn` (18p/1xf).

Gud Boi de3dc2ded0 Port `test_nested_multierrors` off `run_in_actor`
Third `test_cancellation.py` group of the `run_in_actor` removal
(#477),

- `spawn_and_error` fans out each level's erroring one-shots as
  concurrent `to_actor.run(fn, an=an)` tasks in a local `trio`
  task-nursery (recursing per spawner subactor), as does the
  test-body's top-level spawner loop.
- the deterministic exact-breadth nested-BEG shape dies with the
  legacy teardown-reap: each level now groups whatever subset of
  sub-tree errors relay before the first one's cancel wins, and
  a single-member group gets unwrapped by the runtime's own
  `collapse_eg()` at every actor boundary — so a fully-raced
  tree relays a bare `RemoteActorError` chain.
- loosen the shape walk accordingly: accept a lone
  `RemoteActorError` or a 1..breadth group whose members box
  `ExceptionGroup` (multi-relay), `AssertionError` (collapsed
  leaf chain), `RemoteActorError` (re-boxed collapsed chain) or
  `BaseExceptionGroup` (runtime reap-deadline `Cancelled`
  upgrade); fold the windows-only tolerances into the same walk.
- raced sibling `trio.Cancelled`s are now ABSORBED by the
  task-nursery instead of landing in the group, so the MTF
  shape-mismatch xfail should consistently xpass — note added to
  drop the marker once CI confirms.
- add an `else: pytest.fail()` so a silently-clean tree can no
  longer pass.

Gate: both depths green on `trio` (10 consecutive runs) +
`mp_spawn`.

Gud Boi f81f7d40c3 Fix unbound `timeout` under non-trio/MTF backends
`test_nested_multierrors`'s backend/depth budget `match` only
carries arms for the `trio` + `main_thread_forkserver` spawn
backends, so running under any other (e.g. `mp_spawn`) leaves
`timeout` unbound and crashes with an `UnboundLocalError` at the
headroom-scaling below. Add default per-depth arms riding the MTF
budgets (same per-spawn round-trip cost class).

Gud Boi f4f3034555 Port `test_some_cancels_all` off `run_in_actor`
Second `test_cancellation.py` group of the `run_in_actor` removal
(#477),

- one-shot subactors now run as concurrent `to_actor.run(fn,
  an=an)` tasks in a local `trio` task-nursery, so their errors
  raise WHILE the actor-nursery block is open (vs the legacy
  teardown-reap) and the first error cancels sibling one-shots.
- wrap the task-nursery in `collapse_eg()` so the deterministic
  single-error cases still surface a bare `RemoteActorError`.
- loosen the group-shape assertion: the relay-vs-cancel race
  populates anywhere from 1 to `num_actors` `RemoteActorError`s
  (the exact-`num_actors` BEG was `run_in_actor`'s
  reap-all-at-teardown); group members are always
  `RemoteActorError` now since sibling `trio.Cancelled`s are
  absorbed by the task-nursery.
- move the daemon-portal call loop inside the task-nursery body
  so the sleep-forever one-shot case is cancelled by the daemon
  error raise.
- rename the `*run_in_actor*` param ids to `*one_shot*`.

Gate: 6 passed on both `trio` + `mp_spawn` backends.

Gud Boi e824e6b768 Port `test_cancellation` multierror cluster off `run_in_actor`
First group of the `test_cancellation.py` `run_in_actor` removal
(#477),

- `test_remote_error` -> blocking `to_actor.run()` (single erroring
  one-shot; a bad-arg `TypeError` still relays as a
  `RemoteActorError`).
- `test_multierror` -> concurrent fan-out via
  `gather_contexts([p.open_context(assert_err_ctx) ...])` over
  `start_actor()` portals. NB `gather_contexts` is cancel-on-first
  so the 2nd errorer is usually cancelled before relaying its own
  exc and the pair collapses to a single `RemoteActorError` (vs the
  legacy reap-all-at-teardown `BEG`-of-N) — the assertion now
  accepts either shape.
- delete `test_multierror_fast_nursery` — a 25-actor stress test of
  `run_in_actor`'s teardown-reap; no analogous surface under the
  `to_actor` fan-out.
- add an `assert_err_ctx` `@context` shim for the `open_context`
  fan-out.

Remaining `test_cancellation` groups (some_cancels_all, nested,
SIGINT, sync-blocking) still on `run_in_actor` — ported next.

Gud Boi 0835963fa2 Port `test_registrar` off `run_in_actor`
Two sites migrated (#477 removal),

- `test_trynamic_trio`: donny + gretchen each wait on the *other*
  to register, so they must run CONCURRENTLY — was two
  non-blocking `run_in_actor()`s awaited after; now two
  `to_actor.run()` one-shots scheduled into a local `trio`
  task-nursery.
- the unregister-on-cancel cluster test: its non-streaming branch
  spawned `run_in_actor(trio.sleep_forever)` purely to keep each
  subactor alive + registered — a `start_actor()` daemon does that
  without a "main" task, so the spawn loop collapses to the same
  `start_actor()` the streaming branch already used.

Suite: 16 passed.

Gud Boi 4e4191701c Port `test_pubsub` off `run_in_actor`
`test_multi_actor_subs_arbiter_pub` used `run_in_actor()` to spawn
two forever-ish subscriber actors and hold their portals for a
later `cancel_actor()` (its `.result()` was commented out exactly
because `subs()` never cleanly returns). That deferred-spawn +
cancel shape isn't a blocking `to_actor.run()`, so convert to the
successor primitives (#477 removal),

- `start_actor()` per subscriber — keeps the portal for the
  existing `cancel_actor()` teardown,
- run `subs()` on each via a background `Portal.run()` task in a
  local `trio` nursery so both subscribe concurrently with the
  test's `wait_for_actor` / topic checks,
- each bg runner swallows the `RemoteActorError`/`ContextCancelled`
  that `cancel_actor()` relays; a trailing `tn.cancel_scope.cancel()`
  drops any lingering runner.

Suite: 8 passed.

Gud Boi 19d0e9cb78 Port `test_spawning` off `run_in_actor`
Migrate all 4 sites to blocking `tractor.to_actor.run()` (#477
removal),

- rename the two API-named tests to `test_to_actor_run_*`
  (`same_func_in_child`, `can_skip_parent_main_inheritance`) —
  they exercise the same spawn / `inherit_parent_main` path via
  the successor API.
- the recursive `spawn()` helper drops its white-box
  `an._children` / portal-`_peers` asserts (which probed
  `run_in_actor`'s portal + nursery-tracking internals);
  `to_actor.run()` returns the result and reaps internally, so
  keep the user-facing `result == 10` check.
- `test_most_beautiful_word` drops the 2nd `wait_for_result()`
  (the legacy result-cache re-fetch) — `to_actor.run()` delivers
  the value once, no cache.

Suite: 9 passed.

Sole call-site: `run_in_actor(sleep_back_actor, ...)` ->
blocking `tractor.to_actor.run(..., an=n, ...)` (#477 removal).
The RPC-callback subactor is awaited in-caller instead of
reaped at nursery teardown; `name=`/`enable_modules=` map to
`to_actor.run()`'s same-named params, the rest to `**fn_kwargs`.

Sole call-site: an inlined `run_in_actor(...).result()` ->

Behaviour identical — the one-shot's result/error is awaited
in the caller's task rather than reaped at nursery teardown;
the enclosing `move_on_after` still cancels the sub in the
`error_in_child=False` case.

First test-file of the #477 `.run_in_actor()` removal (blocking
`to_actor.run()` is the successor; the legacy non-blocking one-shot
is dropped, not replaced). All 9 call-sites migrated,

- blocking result/error/streaming-result tests -> `to_actor.run(fn,
  an=an, ...)`; the "streaming" ones stream aio<->trio INSIDE the
  subactor so the caller only awaits the final result.
- forever-task + cancel tests (`test_tractor_cancels_aio`,
  `test_trio_cancels_aio`) -> `start_actor()` +
  `Portal.open_context()` + cancel — can't block on a
  never-returning task. Adds a small `sleep_forever_aio_ctx`
  `@context` shim.
- greens the red `test_tractor_cancels_aio` anti-hang guard from
  the prior commit: under the correctly-scoped API the wait is
  bounded by the caller's cancel scope, so the hang is structurally
  gone — not patched.

Suite: 34 passed, 2 xfailed (trio backend).

Wrap `test_tractor_cancels_aio`'s `main()` in a
`trio.fail_after(9 * cpu_perf_headroom())` so a wedged remote
runtime can't hang the test forever. This is the blessed
anti-hang guard here bc `pytest-timeout`'s global cap is
intentionally off (it breaks `trio` under the fork backends,
per the `pyproject` NOTE).

The cap is generous + CPU-headroom-scaled bc it's an anti-hang
guard, not a perf assertion. Motivated by the
`._ria_nursery`-removal regression where a wedged ria-reaper
once hung this exact test indefinitely.

The fresh reap-coordination maps still used legacy `.uid` tuples even
though process monitors and channels carry complete `Aid` identities.
This extended the legacy key format into new private state.

Key both reap maps by `Aid` and derive `.uid` only when accessing the
existing `_children` map. UUID-based `Aid` hashing lets the subactor
and decoded channel identities resolve the same synchronization state.

Update registration tests to exercise the full identity keys.

Gud Boi 2f86dd1a33 Assert paired `ActorNursery` reap state
`._mark_child_reaped()` previously discarded the reap-request event
without checking that its completion-event peer existed. A one-sided
entry would silently lose process-reap synchronization.

Capture both pops and assert paired presence while allowing the valid
both-absent startup-failure path. Keep an unset request valid because
backend cancellation can reap immediately after registration.

Extend graceful and failed-cancel-ack runtime tests to require all
child and reap mappings empty before `to_actor.run()` returns.

Gud Boi 88d538e3a6 Share `Context.cancel()` deadline with frame sends
A parent-side ctx cancel timeout previously bounded only the
remote `_cancel_task` ack. Complete-frame `send_all()` shielding
could hold request publication forever when a peer stopped reading.

Compute one absolute deadline and pass it through `._run_from_ns()`
so transport publication and the ack wait consume the same timeout
budget. Add a mock-clock regression which stalls the private RPC
under a nested shield and proves the transaction returns on time.

Gud Boi 086962ca36 Preserve cancellation over shielded `send_all()` errors
The frame-publication shield added in `88a23449` checks for
pending cancellation only after a successful write. If actor
teardown closes the stream first, `ClosedResourceError` escaped
as `TransportClosed` and could defeat the caller's cancel scope.

Check for pending cancellation on the transport-error path before
normalizing the close. Genuine stream errors retain their existing
translation when no cancellation is active.

The cancellation-first path can swap which nested debugger
intermediary renders as the immediate source vs. relay. Keep
assertions over both actor levels while accepting either valid role.
